Warning Light is an ambient/drone recording project primarily featuring multi instrumentalist Drew Haddon. The band has existed in various forms since 2003, and though formerly based out of Asheville, North Carolina is now in Atlanta, Georgia.

Warning light may refer to:

• Aircraft warning lights, a device used on radio masts and towers and other tall structures to prevent collisions.
• Check engine light
• An automotive Idiot light used instead of a gauge that requires interpretation.
